Optimal Voltage Regulation on Medium Voltage Line In Rural Area Using DIgSILENT

Abstract: The present work features an analysis of the voltage levels in the Quevedo Sur substation, which has a 7.9 km route of three-phase 4/0 AWG ACSR feeder, where it was found that the voltage levels obtained from the feeder do not allow the proper functioning of the triphasic motors that contain the pumping machines used in the irrigation area, located in Hacienda JJ. Through the implementation of the DIgSILENT program, the collected data was used, and proceeded with the realization of a single-line diagram, then the percentage of voltage drop that exits in the feeder could be visualize through the simulation of power flow and voltage profile, in turn, the minimum and maximum voltage points were observed along the three-phase line, and the most convenient location for the voltage regulators was estimated by implementing the analytical module called ''Step-Voltage Regulator'', which main function is to verify and correct the voltages that are not in the allowed range according to resolution No. ARCERNNR-017/2020.
